<br>
by the way it is interesting for me to hear about EDK 10.1 from u steve, <br>
EDK 9.2 has been around just for a little time and you are going to 10.1?<br>
<br>
What about future plan of xilinx about Virtex-5 FX? does this tool consider
that? <br>
the future plan is really important for our development team. let me give a
simple example, our dev team worked on the design of our system based on PLB
and OPB buses for some thing near 6 month, just then EDK 9.2.02 released and
suddenly we forced to change all of the designs and to define new activities
specially focusing on MPMC. we did never consider MPMC before, but the release
of EDK 9.2 changed every thing. <br>
<br>
Now, that would be nice, if we can know your future plan a little, that would
help us to generate correct and real gant charts. and to assign human resources
correctly. this is also true for the project budget. We know that Virtex-5
devices are really capable of doing better things than Virtex-4, specially the
PCI express option is great and very usable for us, but we have not moved to
virtex-5 yet, because there is no FX series or at least we do not know your
plan about it. Our managers we seriously asking us if we have to move to
Virtex-5 soon, we did not have any reasonable answer for them because we do not
have any info from u at all.<br>
<br>
thanks<o:p></o:p></span></font></p>

Ah, thanks mike... you knocked the answer loose out of my brain...<br>
<br>
In EDK 9.2., the ll_temac generates either SDMA or FIFO defines, as necessary.<br>
The platform data structure contains entries for both, with the correct ones being
ignored. In order to get the code to compile, there are some defines in
xparameters.h which have:<br>
<br>
#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR<br>
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR 0xdeadbeef<br>
#endif<br>
#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_DMATX_INTR<br>
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMATX_INTR 0xdeadbeef<br>
#endif<br>
#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_DMARX_INTR<br>
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMARX_INTR 0xdeadbeef<br>
#endif<br>
<br>
after including xparameter_ml403.h<br>
<br>
I'm guessing maybe you overwrote the xparameters.h file and got rid of these
redefines? You can define it to be whatever you want, since the value
will be ignored if you are using SDMA.<br>
<br>
In EDK 10.1, the BSP generator will always generate all the defines (even ones
which are not sensible in the current configuration), which avoids the above
annoyances.<br>

That interrupt is defined if you build a xps_ll_temac with the<br>
xps_ll_fifo interface. Since you already stated that you're using the<br>
mpmc, I'm going to assume that you have it connected to a SDMA<br>
controller on the mpmc. As such the driver should be looking for that<br>
definition, and not the FIFO interrupt. I don't have your version of the<br>
virtex_devices.c to have a reference as to how the platform device is<br>
being defined, so hopefully either Stephen N can chime in w/ more<br>
information, or point me to the version of the virtex_devices.c that<br>
you're using and I can try to provide some more assistance.<br>

<br>
All,<br>
<br>
that should be a small problem, and i think that its solution should be<br>
simple,<br>
<br>
I generate a base system using EDK 9.2.02 , the base system contains<br>
XPS_LL_TEMAC , MPMC and other components,<br>
I generate the software libraries and copy xparameters file into proper<br>
kernel folder. I configure that kernel and add kernel support for<br>
XPS_LL_TEMAC.<br>
<br>
while doing make I encounter this error:<br>
<br>
arch/ppc/syslib/virtex_devices.c:455: error:<br>
'XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR' undeclared here (not in a<br>
function)<br>
<br>
I think that this definition should be available in xparameters_ml403.h<br>
file but i see that there is no such definition.<br>
I added a dummy definition for myself there to complete kernel<br>
compilation, don't know the correct value for it of course.<br>
<br>
thanks<br>
<br>
<br>
